end view thereof; Fig. 5, a detail side view,

and Fig. 6, a detail top view, on an enlarged scale, of the peelingmechanism.

This invention relates to new mechanism for peeling potatoes; and itconsists, first and principally, in the use of rotary spring-arms thathave roughened faces adapted to rasp off part of the peel of the potato,and also in the combination of these arms with mechanism for supportingand for feeding the potatoes through the machine.

In the drawings, the letter Arepresents the frame of myiinprovedmachine, in which frame is hung the shaft B, which carries thepeelingarms 0, and to which rotary motion can be imparted by suitablegearing from a hand-crank, a,orfromothersuitablehandor'otherpower. Inthe framing A is also hung the shaft of a roller, D, parallelwiththeshaftB. Below the roller D is fastened abar, b, carrying teeth d,that extend toward the shaft B, as shown in Figs. 1 and 3. The peelersOon the shaftB are shown enlarged in Figs. 5and 6. Thesaid shaftB carriessuitably-spaced brackets a, each having three (more orless)radially-projecting arms,f. In the ends of these arms f are pivoted thecurved peelerarms (I. The convex sides of these pceler-arms areroughened, file-fashion, as at 9. Each peeler-arm O has at its inner enda projecting lug, h, which prevents said peeler-arms bein gswun goutwardfarther than shown by full lines in Fig.5, the lug coming incontact in that position with the arm f of the bracket; but the said lugdoes not prevent the peeler-arm being folded toward the shaft B, asindicated by dotted lines in Fig. 5. A stout spring, 6, held to thebracket 6, bears on the lug h, and has a tendency to hold the arm 0 inthe position shown by full lines in Fig. 5; but -the spring will yieldif pressure is brought against the convex side of the arm 0. The tensionof the spring i can be regulated by a suitable screw,

j, which has its bearings in one of the armsf.

It will be seen that for each set of three (more or less) arms, 0, thereis an equal number of of springs, 71, and their appurtenances. The

shaft B has its several brackets e e properly spaced, and each of thesebrackets carries its series of arms 0, and these arms are so spaced onthe shaft that when the shaft B is revolved they can pass through thespaces formed between the teeth d of the rake I) d. The roller D isribbed and carries a spiral blade, I, as shown. It is also revolved bysuitable connection with the driving mechanism. Above the roller D is abar, m, to prevent the potatoes being thrown up by the revolution ofsaid roller. The parts B and D, with their appurtenances, are confinedin a drum, E, of which the lower part is hinged, sp that it can be letdown to discharge its contents. \Vithin the upper part of the drum E isa sprinkler, 'n, which is connected with aWvater-supply pipe or vesselto throw a spray of water over the potatoes being peeled. The potatoesare supplied to one end of the machine through a hopper, F, anddischarged at the other end of the machine through a conduit, Gr.

The operation of the machine is as follows: The potatoes to be peeledare fed by the hop per F upon one end of the rake b d. The shaft B isthen revolved in the direction of the arrow shown in Fig.1, so as tobring its rasping or roughened spring-arms O in contact with thepotatoes, which they press against the ribbed roller D, said rollerbeing roughened or ribbed to give a good holdingsurface to the potatoes.Gradually, however, by the rotation of the roller D, its spiral blade 1moves the potatoes on the rake-teeth d in the direction shown by thearrow in Fig. 3-that is to say. toward the discharge-conduit Gr. Bycontact with the roller D the potatoes are revolved, and by the blade 1they are mo 'ed longitudinally, and are thus gradually fed through themachine, exposing, whileinmotipm their several faces to the action ofthe roughened springarms until their peel has been taken entirely off bysaid spring-arms. The water necessary to the operation is supplied bythe sprinkler n, and the peels that are taken off the potatoes are, bythe arms (J, carried into the lower part of the drum E, which inoperation will be nearly full of Water from the sprinkler n. The surpluswater can from time to time or continuously be let off through a faucet,0.

The spiral blade L, instead of being rigidly fixed upon the drum D, maybe made to simply surround the same and have its own independentrotation imparted to it, in which case it will connect with looseflange-like rings that embrace the shaft of the roller D, near the endsthereof.

I have described this machine as intended to peel potatoes; but ofcourse it may be used to peel other vegetables or fruits, and 1 do notlimit myself to the use of the machine for application on any particularsubstance.

It is quite evident that, according to the size of each potato, theposition of each arm 0 that comes in contact with it will be variedwhile so in contact.

I claim 1. Therotatingspring-armsO,combined with a support for thepotatoes to be peeled, and with a rest against which they are pressed,and with mechanism for feeding the potatoes, substantially as described.

2. The combination of the shaft B with the bracket 0, having armsf, andwith the pivoted arms 0, that are roughened at g, lugs h, and spring 2',substantially as specified.

3. The combination of the shaft B, having the roughened spring-arms G,with the supporting-teeth d, roller D, and feeding-blade Z,substantially as specified.

4. The combination of the shaft B, having roughened springarms 0, withthe roller 1) and rod m, and With devices for supporting andlongitudinally moving the potatoes, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
